A secure and efficient mobile IP (MIP) registration protocol using certificateless signature scheme is proposed. The protocol minimises the registration time through minimal usage of an efficient certificateless signature scheme between a foreign agent (FA) and a home agent (HA). Protocol parameters can be kept resynchronised by reusing the initial values in the MIP registration in case the syn...

-In next-generation wireless networks, mobile nodes (MNs) need to freely change their network attachment point while communicating with others. Accordingly, it is crucial for mobile operators to provide efficient seamless mobility support. Several mobility protocols have been standardized by the working groups of the Internet Engineering Task Force (IETF). However, none of them can provide seam...

In Mobile IPv6 especially in Hierarchical Mobile IPv6 (HMIPv6), Mobile Node’s handoff performance is greatly impaired by the Duplicate Address Detection (DAD) procedure for the newly formed Care-of Address. Based on the data gathered from our HMIPv6 test bed, this paper analyzed the origin of such performance degradation. To alleviate the impact of DAD on handoff performance, Greg Daley et al p...

Cellular is the inevitable architecture for the Personal Communication Service system (PCS) in the coming future. Access to the Internet via cellular networks is expected to become an essential portion of future wireless service offerings. Providing seamless support for IP based packet switched services has become an important issue. The Internet Engineering Task Force’s (IETF’s) mobile IP prot...

Mobile IPv6 is considered to be one of the key technologies for realizing mobile Internet which enables seamless communication between fixed line and wireless access networks. In this paper, we introduce the basic concept of Mobile IPv6 and describe the detail procedure of handoff of mobile terminal. We analyze its effectiveness of Mobile IPv6 handoff by using Network Simulator 2 and constructe...

Problem statement: IETF has introduced Hierarchical Mobile IPv6 (HMIPv6) to support mobility problem in the next generation Internet Protocol (IPv6). The key concept behind this protocol is the usage of Mobility Anchor Point (MAP) located at any level router of network to support hierarchical mobility management and seamless handover. The distance MAP selection in HMIPv6 causes MAP overloaded a...
